Here, you are checking for a symbol named DEBUG. If it is present, you dump out a number of

interesting statistics using some static members of the System.Environment class. If the DEBUG sym-

bol is not defined, the code placed between #if and #endif will not be compiled into the resulting

assembly, and it will be effectively ignored.
